TB-500 dilution calculator

Research material: lyophilized powder; vial sizes: 5 mg, 10 mg. Documented research protocol: 2x weekly (loading); range 2000–5000 mcg; step increments 500 mcg; cycle: 4–6 weeks loading, then reduced maintenance; 4 weeks off before the next loading block. Record evidence grade: B; note: loading/maintenance pattern from community practice; Tβ4 biology documented, injectable human dosing not established.

Calculator computes: final concentration per vial; volume to draw for target mcg; syringe unit conversion; precision warning for small volumes; confidence grade B for the referenced record. Outputs are for research planning only.
